71    
72     <p>
73     Gentoo Linux can be installed using a <e>stage3</e> tarball file.
74     Such a tarball is an archive that contains a minimal environment from
75     which you can succesfully install Gentoo Linux onto your system.
76     </p>
77    
78     <p>
79     Installations using a stage1 or stage2 tarball file are not documented in the
80     Gentoo Handbook - please read the <uri link="/doc/en/faq.xml#stage12">Gentoo
81     FAQ</uri> on these matters.

87     <title>Gentoo Universal Installation CD</title>
88     <body>
89    
90     <p>
91     An Installation CD is a bootable medium which contains a self-sustained Gentoo
92     environment. It allows you to boot Linux from the CD. During the boot process
93     your hardware is detected and the appropriate drivers are loaded. The Gentoo
94     Installation CDs are maintained by Gentoo developers.
95     </p>
96    
97     <p>
98     There currently are two Installation CDs available:
99     </p>
100    
101     <ul>
102     <li>
103     The Universal Installation CD contains everything you need to install
104     Gentoo. It provides stage3 files for common architectures, source code
105     for the extra applications you need to choose from and, of course, the
106     installation instructions for your architecture.
107     </li>
108     <li>
109     The Minimal Installation CD contains only a minimal environment that allows
110     you to boot up and configure your network so you can connect to the
111     Internet. It does not contain any additional files and cannot be used
112     during the current installation approach.
113     </li>
114     </ul>
115    
116     <p>
117     Gentoo also provides a Package CD. This is not an Installation CD but an
118     additional resource that you can exploit during the installation of your Gentoo
119     system. It contains prebuilt packages (also known as the GRP set) that allow
120     you to easily and quickly install additional applications immediately after the
121     Gentoo installation and right before you update your Portage tree.
122     </p>
123    
124     <p>
125     The use of the Package CD is covered later in this document.
126     </p>

131     <title>Choosing a userland</title>
132     <body>
133    
134     <p>
135     On PPC64, the kernel is 64-bit and the <e>userland</e> can be 32-bit or 64-bit. The
136     userland is basically the applications you are running, such as
137     <c>bash</c> or <c>mozilla-firefox</c>. They can be compiled and run in either
138     64-bit or 32-bit modes. The Gentoo/PPC64 team provides both 32-bit and 64-bit
139     userlands, so which one should you use?
140     </p>
141    
142     <p>
143     You may have heard that 64-bit applications are better, but in fact, 32-bit
144     applications take up slightly less memory and often run a little bit faster than
145     64-bit applications.
146     </p>
147    
148     <p>
149     You really only need 64-bit applications when you need more memory than a 32-bit
150     userland allows, or if you do a lot of 64-bit number crunching. If you run
151     applications that require more than 4GB of memory or you run scientific
152     applications, you should choose the 64-bit userland. Otherwise, choose the
153     32-bit userland, as it is recommended by the Gentoo/PPC64 developers.
154     </p>
155    
156     <p>
157     Additionally, the 32-bit userland has been available in Portage longer than the
158     64-bit userland has. This means that there are more applications tested in the
159     32-bit userland that just work "out of the box." Many applications compiled for
160     the 64-bit userland may be just as stable as the 32-bit version, but they
161     haven't been tested yet. Though testing isn't difficult to do, it can be
162     annoying and time consuming if you want to use many untested 64-bit
163     applications. Also, some programs just won't run in the 64-bit userland until
164     their code is fixed, such as OpenOffice.
165     </p>
166    
167     <p>
168     The Gentoo/PPC64 team provides stages and Package CDs for both 32-bit and 64-bit
169     userlands, so no matter which one you choose, you'll be able to successfully
170     install Gentoo and get a full system up and running with minimal fuss.

178     <title>Download, Burn and Boot a Gentoo Installation CD</title>
179     <subsection>
180     <title>Downloading and Burning the Installation CDs</title>
181     <body>
182    
183     <p>
184     You can download the Universal Installation CD (and, if you want to, the
185     Packages CD as well) from one of our <uri
186     link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
187     the <path><keyval id="release-dir"/>installcd</path> directory; the Package CDs
188     are located in the <path><keyval id="release-dir"/>packagecd</path> directory.
189     </p>
190    
191     <p>
192     Inside those directories you'll find ISO files. Those are full CD images which
193     you can write on a CD-R.
194     </p>
195    
196     <p>
197     After downloading the file, you can verify its integrity to see if it is
198     corrupted or not:
199     </p>
200    
201     <ul>
202     <li>
203     You can check its MD5 checksum and compare it with the MD5 checksum we
204     provide (for instance with the <c>md5sum</c> tool under Linux/Unix or
205     <uri link="http://www.etree.org/md5com.html">md5sum</uri> for Windows). How
206     to verify MD5 checksums with Mac OS X is described in the <uri
207     link="/doc/en/gentoo-ppc-faq.xml#doc_chap1">Gentoo PPC FAQ</uri>.
208     </li>
209     <li>
210     You can verify the cryptographic signature that we provide. You need to
211     obtain the public key we use (0x17072058) before you proceed though.
212     </li>
213     </ul>
214    
215     <p>
216     To fetch our public key using the GnuPG application, run the following command:
217     </p>
218    
219     <pre caption="Obtaining the public key">
220     $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 0x17072058</i>
221     </pre>
222    
223     <p>
224     Now verify the signature:
225     </p>
226    
227     <pre caption="Verify the cryptographic signature">
228     $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
229     </pre>
230    
231     <p>
232     To burn the downloaded ISO(s), you have to select raw-burning. How you
233     do this is highly program-dependent. We will discuss <c>cdrecord</c> and
234     <c>K3B</c> here; more information can be found in our <uri
235     link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
236     </p>
237    
238     <ul>
239     <li>
240     With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
241     file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's device
242     path).
243     </li>
244     <li>
245     With K3B, select <c>Tools</c> &gt; <c>Burn CD Image</c>. Then you can locate
246     your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
247     </li>
248     </ul>

253     <title>Booting the Installation CD on an Apple</title>
254     <body>
255    
256     <p>
257     Please check the <path>README.kernel</path> on the Installation CD for the
258     latest information on how to boot various kernels and getting hardware support.
259     </p>
260    
261     <p>
262     Place the Installation CD in the CD-ROM and reboot the system. Hold down the
263     'C' key at bootup. You will be greeted by a friendly welcome message and a
264     <e>boot:</e> prompt at the bottom of the screen.
265     </p>
266    
267     <p>
268     You are also able to tweak some kernel options at this prompt. The following
269     table lists the available boot options you can add:
270     </p>
271    
272     <table>
273     <tr>

275     <th>Description</th>
276     </tr>
277     <tr>
278     <ti><c>video</c></ti>
279     <ti>
280     This option takes one of the following vendor-specific tags:
281     <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>, <c>aty128</c>, <c>nvidiafb</c>
282     or <c>ofonly</c>. You can follow this tag with the resolution and
283     refreshrate you want to use. For instance
284     <c>video=radeonfb:1280x1024@75</c>. If you are uncertain what to choose,
285     <c>ofonly</c> will most certainly work.

329     <p>
330     Please check the <path>README.kernel</path> on the Installation CD for the
331     latest information on how to boot various kernels and getting hardware support.
332     </p>
333    
334     <p>
335     Most modern pSeries servers can boot from the CDROM drive through SMS ('1' when
336     the “IBM IBM IBM” messages flash across the console). On some older pSeries
337     boxes, sometimes the cds might not autoboot. You might have to set up your
338     cdrom as a bootable device in the multi-boot menu. (F1 at startup) The other
339     option is to jump into OF and do it from there:
340     </p>
341    
342     <ol>
343     <li>
344     Boot into OF (this is 8 from the serial cons or F8 from a graphics
345     cons, start hitting the key when you see the keyboard mouse etc etc
346     messages.
347     </li>
348     <li>Run the command 0> boot cdrom:1,yaboot</li>
349     <li>Stand back and enjoy!</li>

354     <subsection id="booted">
355     <title>And When You're Booted...</title>
356     <body>
357    
358     <p>
359     You will be greeted by a root ("#") prompt on the current console. You can also
360     switch to other consoles by pressing Alt-fn-F2, Alt-fn-F3 and Alt-fn-F4. Get
361     back to the one you started on by pressing Alt-fn-F1.

364     <p>
365     If you are installing Gentoo on a system with a non-US keyboard, use
366     <c>loadkeys</c> to load the keymap for your keyboard. To list the available
367     keymaps, execute <c>ls /usr/share/keymaps/i386</c>.
